CD−34°8618, also known asKELT-13 orWASP-167, is a yellowish-white huedstar located in the southernconstellation ofCentaurus. It has anapparent magnitude of 10.52,[3] making it readily visible in medium sizedtelescopes, but not to thenaked eye. Based onparallax measurements from theGaia spacecraft, the object is estimated to be approximately 1,350light years away from theSolar System.[2] It appears to be drifting closer to it, having aradial velocity of−0.53 km/s.[5]
WASP-167 has astellar classification of F1 V,[4] indicating that it is an ordinaryF-type main-sequence star that is generating energy viahydrogen fusion at its core. At present it has 1.59 times themass of the Sun[4] and 1.94 times theradius of the Sun.[6] It radiates 8.34 times theluminosity of the Sun[7] from itsphotosphere at aneffective temperature of6,909 K.[7] WASP-167 has aniron abundance 26% above solar levels,[4] making it metal enriched — common among planetary hosts. The object has completed 63% of itsmain sequence lifetime[2] at an age of 1billion years.[4] Like many hot stars, WASP-167 spins rapidly, having aprojected rotational velocity of52 km/s,[8] meaning it completes a rotation under 2days.[4]
AHot Jupiter was discovered in a tight, 2day retrogradeorbit the star by theSuperWASP and theKELT. WASP-167 was observed to have non-radialpulsations, which might be caused by the planet's close orbit. It has anequilibrium temperature of2,329±64 K and is nearlytidally locked, similar toMercury.[4]
